AB  - Class D switching amplifiers can, if optimally designed, achieve performance results comparable, both electrically and acoustically, to the very best class A units. Design parameters and steps needed to achieve these results are considered in detail. Data are presented showing that at least seven critical design criteria must be met if high performance is to be obtained. Failure to implement any one of these seven will result in a pulse-width-modulated amplifier of moderate to poor performance, and one that is likely to be subject to considerable spreads in production.
